@jtdolphins,
That is a really cool idea. I was homeschooled for awhile and I would have LOVED an ereader for my text books.
Totally self-promoting here, but if the moms want a "how to get library books" video to refer to if they forget your instructions I HAVE MADE ONE.

Dunno how useful it will be, but I made it for MY mom, so there's that.
